Detailed Description
Referring to fig. 1-4, the invention provides a highway passing card throwing arrangement device, which comprises a card throwing box 1 arranged in a case, and is characterized in that: the card-throwing box 1 is provided with a camera 2 for detecting whether a pass card exists in the card-throwing box 1, a reader 5 for performing read-write operation on the pass card, and a position adjusting device for adjusting the gesture and the position of the pass card. The position adjusting device comprises a belt conveying assembly for receiving the pass card of the driver throwing the card throwing box 1 and driving the pass card to horizontally move, and a baffle assembly for blocking the pass card on the belt conveying assembly so as to adjust the position of the pass card or opening the opening on the card throwing box 1 to release the pass card on the belt conveying assembly so as to recover the card.
Referring to fig. 1, the opening of the card-throwing box 1 is toward the outside, i.e., the driver side, to facilitate the throwing of a card by the driver. The camera 2 is arranged at the opening of the middle part of the top of the card throwing box 1. The camera 2 is fixed at the opening of the top of the card throwing box 1 through a connecting bracket 3. The camera 2 is used for finding a view to the conveyor belt 8 in the belt conveying assembly, is arranged in the middle of the top of the card throwing box 1, so that the camera 2 can have an optimal shooting view field, and whether a pass card is thrown onto the conveyor belt 8 or not is judged by processing video data collected by the camera 2, and the position and the gesture of the pass card are known.
In detail, the video data collected by the camera 2 is processed to obtain whether the pass card enters the belt conveying assembly, and the processing of the video data comprises the following steps.
A. And D, judging whether an object enters or not by performing motion detection on the video data, and if so, executing the step B.
B. C, obtaining a motion area of the object through background analysis, carrying out edge analysis on the motion area to obtain edge characteristics of the motion area, judging whether the minimum circumscribed rectangular area of the edge characteristics accords with the size of the pass card, if so, executing the step C, otherwise, driving the object to move outwards by the belt conveying assembly, and prompting a driver to take out the object through voice or light.
Further, by Δf (x, y) =abs|f i (x,y) - F i-1 Judging whether a moving object exists or not (x, y) |, wherein i is a video stream frame sequence number, F i (x, y) is the current frame, F i-1 (x, y) is the last frame, x and y are the width and height of the image, respectively, a point of value 0 in ΔF (x, y) indicates that the point has no motion,
when the total number of points with motion is smaller than x y x 0.05, the current frame is considered to have no motion, and then Fi (x, y) is updated as the current background; when Δf (x, y) is greater than x y x 0.05, a moving object is present in the scene, and a moving region P (x, y) is acquired through a point in Δf (x, y) having a value other than 0.
The initial background is the first frame of image data acquired by the camera 2.
At the current frame F i (x, y) removing noise interference before edge extraction, and using Gaussian blur to make the current frame F i (x, y) noise reduction:
gaussian blur: i (x, y) =f i (x, y) Gauss (3, 3), I (x, y) is data after gaussian blur processing.
The data after noise reduction is subjected to edge extraction by using a Canny operator, the edge contour in the scene is extracted,
edge extraction: e (x, y) =i (x, y) =canny (3, 3), E (x, y) is the extracted profile data.
C. And (3) carrying out color analysis on the movement area, if the difference is blue, judging that the object is a pass card, then reading and writing the pass card by the reader-writer 5 or conveying the pass card to the upper side of the reader-writer 5 by the belt conveying component, then reading and writing the pass card by the reader-writer 5 or carrying the pass card to the upper side of the reader-writer 5 after the position adjustment device carries out pose adjustment on the pass card, otherwise, driving the object to move outwards by the belt conveying component and prompting a driver to take out the pass card.
Whether the motion area is blue or not is judged by comparing the trend of the tone scale value of each pixel R, G, B in the image. When M R <M G <M B When the M point is the blue point to be detected, then the value of the point is set to 1 in C (x, y), the value of the point is set to 0 without meeting the condition, and M is the current frame F i One pixel point in (x, y), C (x, y) is the current frame F i (x, y) color profile.
After the position of the pass card is identified in the steps, the coordinate information of the pass card in the video area is obtained and is used by a subsequent position adjusting device or other devices.

5. The highway passing card throwing arrangement device according to claim 4 is characterized in that a travelling wheel (19) is arranged at the bottom of the card throwing box (1), and a bottom plate (20) matched with the travelling wheel (19) is arranged in a bearing bracket (21).
6. The highway access card throwing arrangement according to claim 1, wherein in step B, the current frame F is being subjected to i (x, y) removing noise interference before edge extraction, and using Gaussian blur to make the current frame F i (x, y) noise reduction:
gaussian blur: i (x, y) =f i (x, y) Gauss (3, 3), I (x, y) is data after Gaussian blur processing,
the data after noise reduction is subjected to edge extraction by using a Canny operator, the edge contour in the scene is extracted,
edge extraction: e (x, y) =i (x, y) =canny (3, 3), E (x, y) is the extracted profile data.
7. The card-throwing arrangement for expressway traffic cards of claim 1, wherein in step C, it is judged whether or not the movement area is blue by comparing the trend of the values of each pixel R, G, B in the image,
when M R <M G <M B When M is the blue point to be detected, then the value of the point is set to 1 in C (x, y), the value of the point is set to 0 without meeting the condition, and M is the current frame F i One pixel point in (x, y), C (x, y) is the current frame F i (x, y) color profile.
8. A card throwing type self-service payment machine, which is characterized by comprising the expressway passing card throwing arrangement device as claimed in any one of claims 1 to 7.
